Sales figures weren't the only thing mentioned in Nintendo's financial briefing this week - Satoru Iwata also talked 3DS.
The next portable from Nintendo, currently known as the "3DS", will offer stereoscopic 3D without the need for glasses, but according to the company boss it'll be an optional feature. Without giving too much away, Iwata acknowledged that some players may not want to use the feature and there might be some health side-effects, so outputting in 3D can be disabled.
More information on the 3DS will be available at E3 2010 in June.
